How to grow carrots in Tennessee, step by step
- Prepare the bed. They need six or more hours of sun for the best growth, though four to six hours in partial shade is enough and loose soil at least 12 inches deep, with a pH between 5.5 and 7.0. Dig in compost before planting.
- Sow outdoors (Mar 15 – Apr 3). Space plants about 3 inches apart in rows 12 inches apart, sowing seed ¼ inch deep. It handles frost well, so it can go out before the last frost date. As a cool-season crop it does best before summer heat arrives in Tennessee.
- Water and feed. Give it steady, even moisture, about an inch of water a week from rain or the hose.
- Watch for pests and problems. Pests: carrot rust fly, wireworm, root-knot nematode, aphids. Diseases and disorders: alternaria leaf blight, cavity spot, aster yellows.
- Harvest (from about May 19 – Jun 8). Carrot takes 60-80 days to reach harvest. Never transplant. Keep the surface constantly moist for the slow 2-3 week germination - a board or burlap over the row helps. Needs loose, stone-free soil or roots fork.
